Application led January 14. 1910. Serial No. 537,931.

`ciu'ity and simplicity of attachment, and in euch manner thatend-thrust of the tank is directly sustained by the center-sills; andthe invention has for further objects such other improvements instructure or function as nuiy be found to obtain in tlIe deviceshereinafter described or claimed.r

ln the accompanying; drawings. forminga part of this specification, andin which like reference runnerals indicate like parts in all of thefigtu-es, Figure l is a longitudinal sectional. View of one of theduplicate ends of a tank-car underframe embodying the construction of myinvention, with the upper part of the car-tank broken away; Fig.v 2 is asection on the line --Q of Fig. 1; Fig. 3 is a section on the 'line ofFig. l.

10--10 are theI channel iron center-sills ot the uiulertrame. l1 is thebody bolster Secured to said sills.

12 is the tank; and at each end of 'this tank there is rigidly securedto its bottom the cradle-casting 13, positioned near the body bolsterand on the side-thereof away from the adjacent end of the car. The topmember 14- of this cradle-casting is elongated and shaped to conformwith the curvature oi the portion of the tank bottom to which it isriveted; ,and the shoulders 15 rest upon the top of the upper flanges ofthe channel iron center-sills, thus directly supporting saidcradle-casting upon said centersills. The downward projection 16 of saidcradle-castingl is .fitted down within and between the opposed innerfaces ot the verticle webs of the center-sills, the said casting' beingthus socketed to said sills and holding the tank from lateral movementin reference to the sills. The said downward projection of thecradle-casting is provided with a transverse keyway 17, which registerswith corresponding keyways 18 in the respectively opposed vertical websof the f sills* A horizontal flattened key 19 is passed through thesemutually registering keyways, and is retained in position by thccottcr-pins inserted in'its projecting opposite.

ends. vThis keying of the cradle-casting to the center-sills providesan' extremely sim` ple `and effective securing ot' the tank to thesillsand all end-thrust of the tank, resulting from bulllng)` shocks orother cause, is ldirectly sustained by the sills, being imme-y diatelytransmitted thereto through the faille-castings and the key whereby sindcastings-engage the sills'.

By reason of the tact that the sills thus sustain all end-thrust of thetank, through f the cra(lle-castings thus resting,l upon and' secured tothem'between the body holsters,

the tank head-block 2O is relieved of lill` end-thrust of 'the tank andmay be dispensed with entirely, except 1n so im' as such head-T block isretained as a mere protection to the bottom of the rim of the ytank-end..Dispensing with the head-block is in many instances deemed desirableand of substantial advantage in' the construction of the car. But

when the head-block is present, it may con-" .fcniently be held in placeby the L-shaped .head-block tie-plate 21, whose horizontal memberpassesunder the head-block and isf' secured to the top flanges of -the` sills,and

.85 against the outside face ofv and abovel the* whose vertical memberpro]ects upward head-block, thehead-'bloc'k thus being seated in theangle of'said tie-plate. And thenfthe end 2Q of the tank is convenientlyand ee`ctively secured tothe said head-block tie-plate lby means ,ot thetank-end tie-plate 28 Whose upperll` end is riveted to the conter ofthetank-end and whose lower end is detachably bolted, at 24, to the top ofthe vertical mem` ber of the head-block tie-plate, thus providing anespecially convenient and;- eii'ective means of securing the tank to thesills at each of the extreme ends of the car. n

tain any tendency to lateral swaying of the tank, in reference to theunderframe,A there are also provided, over each body-bolster', a pair ofheel-castings 25,' secured to the lower portion of the side of thetank-bottom over the respectively oppositc'lateral members of the bodybolster` the fiat bottom of each such heel-casting being adopted to makecontact With the top face of the corresponding lateral member of thebody-bolster7 in the manner indicated in Fig. 2. These lateral heelsserve to relieve the cradle-castings, and tlie tank-bottom, of some ofthe strain that would be put upon them by any tendency of To susthe tanklo lateral s\\'a.'ing. The tying` oc of parts as would be involved inthe removal of rivets;-and so also, such keys may be freely put inplace; and eii'eet the cminec.- tion of the sills with thecradle-members, without any such operation as the perinanent heading-upol rivets. lt will also be observed that the heel-castings bear freelyUPON: 21nd' are free of any connection with; the body-holsters; thusproviding.;- 'for the lateral supportot the tank wit-hout prevent-- ingthe l`ree securing` or detaching of the i l i i tank by the mereinserting or removal ot' 3 the aforesaid freely removable key s.

My invention is herein above setiforth as embodied in one particularfern. of cont-he invention hereinafter claimed may. be embodied anddistinguished from any prior device for like purpose.

I claim:

l. In a tank-car, in combination: a tank; center sills; a cradle-memberrigidly secured to the bottom oit the tank and supported upon andsocketcd to the centersills; and a transverse freely removable keypassed through'mutually registering keyways in said center sills` andcradle-ineinbers; substantially as specilied.

2, lin a tank-car, in combination; a tank; Center-sills; a eadie-membi-arigidly secured to the bottom of the tank and supsills; and a transversefreely removable key passed through mutually registering keyrv" t insaid center-sills and cradle-me mbers, substantially as specified.

Pl. In a tank-car, in combination: a tank; center-sills; a cradle-memberrigidly secured to the bottom of the tank and supported upon andsocketed to the center-sills; and a horizontally tansverse freelyremovable key passed through mutually registering key-ways in saidcenter-sills and cradlemember; substantially as specified.
